Super neat idea!

As a DM + general TTRPG lover, I think the real magic is playing with friends so the game can be exactly what the group wants, then each session and campaign can build on each other.

Our group has running jokes that span campaigns and worlds, because we have that shared language from being a group.

With that said, I still think this is a fantastic idea for everyone from all fronts to be able to play the games you like and get exactly what you want out of a game.

I will have to take a look because I have been curious about how to get deeper into this area, possibly for pay. One thought was to start a game shop in my town but I have heard super low margins and just not a great idea.
